Packera multilobata
Packera cardamine
Packera multilobata is abundant and widespread west of the Continental Divide. Both morphology and habitat vary. In colder parts of its range, plants are shorter, caudices are better developed with clustered stems, and leaf lobes are larger. In desert-like habitats, basal leaves are narrower and more finely lobed, the tomentum is often persistent, and stems are usually single.

Of conservation concern.
Packera cardamine is uncommon, rarely collected, and known only from the Mogollon Mountains of New Mexico and the White Mountains of Arizona.
